Event-driven HIV prevention pill for men who have sex with men
This trial tests a new way to take HIV prevention medicine (PrEP) only around the time you have sex, using a pill called TAF/FTC. It aims to see if this 'on-demand' method is effective, safe, and acceptable, and could offer a more flexible option than taking a pill every day.

Interferon gamma for ventilator pneumonia in ICU
This trial tests whether a medicine called interferon gamma can improve outcomes in adults with a first episode of pneumonia that develops after being on a ventilator in the ICU. It is designed for specific ICU timing, infection severity, and immune marker levels, and it compares treatment on top of standard care.
LimogesAges 18 years+ - NCT05814432RecruitingPhase 3
High-dose antifungal for widespread Histoplasmosis in HIV
This Phase 3 trial tests whether a high-dose form of amphotericin B made in tiny fat particles (liposomal amphotericin B) is safer and more effective for treating widespread Histoplasmosis in adults with HIV. It may help people who have a serious, whole-body infection caused by Histoplasma.
Goiânia, GoiásAges 18 years+ - NCT05835206RecruitingPhase 2
